To all whom t may concern:

Be it known that I, FREDERICK H. K rNDL, of Pittsburgh, Allegheny county, Pennsylvania, have invented a new and usetul Unloading Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanyingdraw-y ings,`tornnng part of this specification, 1n which-i,

My invention has relation to unloading apparatus, and more particularly to apparatus vforunloading granular or lump'material such as` ore, from boats or vessels.

ln my prior Patent No. 711,772, dated' October 21st, 1902, I have described andI claimed unloading apparatus of the general character 'of that forming the subject of the present application. The apparatus oniy said patent was shown as especially arranged to be used in the unloading of boats or vessels hy being carried on an overhun'g beam supported on the dock Aenla-riding ad-v jacent to the vessel, and uponwhich the un:

loading apparat-us proper could be moved..

The present invention is designed to pro.-

vide means whereby the lunloading' apparat-us'- rnay be carried directly on vand form v a part. of the equipment'of the vessel so. as l to be available'A for unloading. at anyr doek or wharfat 'whichit may be desired to use it.' A further object of my invention isito im.

features, as hereinafter .pointed out,lwhe'reA etiicient for the particular it is especially intended. U

In the accompanying drawings, the nu- I'neral 2 (Fig. 1),' designates a dockor pier,

purpose for which having railroad tracks 3 thereon extending'4 parallel with'its water edge. In the present i'iistance' two parallel tracks are shown, and

upon which cars 4 may be run to receive the material as it is unloaded. `.5"designates anelevated bin or hopper having a branch d ischarge 6. This bin or hopper receives'tluzv ore or other material discharged by the unloading apparatus, 'and in vturn discharges it into one or bothof the cars 4.. It will be understood, however, that the 'discharge apparatus may here;

from the'un'loadin ceived by anysuita le apparatus','or may-be directed into a pileon the'dock or wh arf, 'y

the arrangement shown being 'illustrative only. Y v

7designates a boat or `vesselhaving a lu ,rality of transverse hatchways 8 exten ing nearly the full width of 'thevessel., Sup `ported, on tracks to span'these'series of 'hatch'.ways and to he moved longitudinally of the vessel over any particular'hatchway, 1s a crane structure 9 upongwlnch my 4unloading. apparatus is carried.' This unloadf' ing apparat-us is in general cf'the character and *arrangement shown in my said patent.-

lt comprises a vertical leg 10,-whic'h, in Fig.

1, is shown as 'olset at its lowe'rend portion- 11, and which is' mounted on the bridge Aof i the crane 9 to be capable'of an up and' down. movement, a rotary movement about a'vertical axis, a tilting movement on the` trunnions 12, and a transverse back and. forth movement on the bridge 9. v. The vertical,` 'movement is effected by means oa motor.' i 13,' which, through suitable gearing 214,; drives pinions 15, which mesh 'with suitable, vert-ical racks 16.011 the leg'structure. (Seel Figs.'1 and 5.) The rotary movementaboutl I a vertical axis 'is effected by means of a ino# tor 16,' which, through a (suitable train of.

gearing 17,' drives a pinion 18j, whichmeshes with the teeth 'of Aan internal circular rack 19;

carried bythe leg structure;V

Asshown lin Fig. 5,"the two motors 13 and 16 are preferably mounted directly on a.

turntable 20 of the leg, at. diam'etrically :op- 5 i posite points so as to assist in balarming.,A 'each other. The tilting movement of-'theleg is effected by., means oftheellectric motor 21 which, through suitahlegearing 22, drives al worm 23, which'meshes with the worm teeth of-a sector 24 secured tothe leg. -(See Figs. i l and 6.)l The .transverse back and forth movement of the leg 'is' .effected b'y means ofk an velec/tric motor Q5, which. through suit-able gearing-.25?dr'lves pinions 27, meshing with? l a rack bar 28 on the crane bridge. The

'traverse of the crane longitudinally of the han for uiting' the snee bucket to dischargi bucket 3l is bucket into fillingl 'shownin said figure when desired.

' 51 the bucket will ing position, and which is operated 'by the cable 34, which passes around a. winding drum 35,driven by an electric motor 36, the drum 35 andthe motor 36 being-tocated at the' top of the leg structure.l 37 is the motor, thereby for tilting-thebucket holder and position. ./Except in the particulars' hereinafter described, these parts aretlie same as inY my said patent, and do not require specific description here. 89 designates a hopper,` into wliiclithe arranged to discharge when ele rated into discharging position, and which is provided with the discharge spout 40. The hopper 39 (see Figs. 1, 2, 3 and 4,), is projvided with brackets 41, which engage vertical `guides 42 on the leg structure, and upon which l,( g'uidessaid hopper and its spout are vertically movable. This vertical movement 'isefe'cted means of an electricmotor 43 mounted on the platform gt4 below the hopper 'and connected thereto. drives gearing 45, which meshes with the teeth of a vertical rack 46 on the legV structure. The hopper has a circular discharge opening 47, to -which l'is ,'tltted .the circular upper portion of the' spout 40,' the, latter having "the flange 48 rotatably fitting a guide 49mm the hopper, whereby thespout may be rotated to different angular positions. The spoilt preferably has a hinged section, as indicated in Fig. 2, and which can be dropped tothe dotted line position This hinged section ris normally supported in discharge position rin *any suitable Way, as byy means of the hook '50. The hopper also carries the dumpingr guides 51, which arede- Signed to be engaged by the dumping roller on the bucket when the bucket is raised into contact therewith. The bucket has one of these rollers at each side; and as these rollers come into engagementwith the guides be tipped forwardly until it has`beenraised sulliciently` to bring the rollers against the upper closed ends of the guides. A Continued upward, movement of the b ucket will lthencause'tlie bucket to turn on i b the rollers 52 as pivots and `effect its: dis'.l charge. The' vertical adjustment of the hopperand spout is ofconsiderable importancfto' the proper use of the` apparatus for unloading vessels, sinceit necessarily occurs I set'at'its lower andBS thegearing driven enlargement 56, which shoulder 57 at the top and at 'eachside of the This motor y able longitudinally of loadingA Vtilting movement of that the height of the vessel with relation to the dock will vary at dilferent times or at different places. In unloading some materiale,- such as coal, it is desirable that there shall be as little fall or drop of the material as' possible, in order to prevent its deterioration or disintegration. By means of the adjustable hopper,the amount of talll or drop can 'in each case be adjusted to a minimum.

In Figs. 8 and 9 I have shown a modifcation of the leg, and detail views of the bucket and its'hqlder. In the lformshown in these figures, the leg instead of bein olfshown in Fig. S. The bucket'is provided at its forward end with a thickened portion or forms the external bucket, this shoulder being arranged to' lit against the open upper or forward endjof the holder, as shown.

holder into which granular or pulverized material can find its wayor be forced is obviated. A similar shoulder 58 may be formed on the bottom of the bucket by means of the cuttingedge or plate 59 sec-ured to the bucket.

As before stated, my improved unloading apparatus is designed to be normally carried' on vthe deck of the vessel. For this purpose,

-the deckfis provided with an additional hatchway` 60 V(see Fig. 7) at someconvenientpoint, through which the leg can be lowered into the hold for storage while the vessel is in transit. By inountinv the unloading apparatus on a crane whic i is movthe vessel, and the unapparatus being movable transversely uponv the crane, it will be apparent that not only allythe hatchways of the vessel, but every portion of each hatchway can be reached to the bestadvantage in effecting the complete` unloadin of the vessel. The verticalmovement of ie leg,r which is rovided is suilicient to enable it to be raised far enou h to clear the solid deck portions bet-Ween t e hatchways in moving longitudinally from one hatchway to another. The tiltin'gunovement of the leg, as Well as the the bucket and its holder, enables the bucket to be forced into the material at the most effective angle; the rotary movement of the leg about a vertical axis enables all parts ofthe vessels hold to e reached, including the corner portions; while the adjustable spout, as before stated, provides for aminimum drop or fall of the discharged materal.

It will be obvious thativarious changes can be made in the details of construction portion, is straight, as siown at 53. TlieLbucket holder 32 is a shell of general rectangular form, open at botliends, -and into which the bucket- 31 can slip, as is ln this manner any opening or space between thebuckct or alsV rnotarios and arrangement of the parts whereby these several movements are ell'ected )vithoutdeparting 'from the spirit and scope'oi' my invention as deiined in the appendfed@ claims.
